Abstract: A system and method for planning a well path is described. An exemplary method comprises defining a proxy constraint volume as a three-dimensional (3D) cellular volume where each cell has at least one value derived from data from a 3D earth model. An initial well path is defined within user defined drilling parameter constraints. The exemplary method comprises defining acceptable constraint parameters to be applied to values derived from an intersection of the initial well path and the proxy constraint volume. If the intersection of the initial well path and the proxy constraint volume is not within the acceptable constraint parameters, the initial well path may be iteratively adjusted to create successive well paths until at least one of the successive well paths is within the acceptable constraint parameters for the values derived from the intersection of the well path and proxyconstraint volume.

Granted: 2020-08-04
Abstract: The present disclosure relates to a method and device for evaluating a wooden board with an elongated direction. Data indicating fiber orientation over the surface of the board is acquired and for a number of board sub- portions a nominal local modulus of elasticity, MOE, is determined based on the fiber orientation data and a nominal material parameter. A nominal global MOE in the elongated direction for the wooden board as a whole is generated and compared with a secondary global MOE. Based on the fiber orientation data and this comparison an estimated local modulus of elasticity, MOE, in said elongated direction is generated for a number of board sub-portions. This data may be used e.g. for reliable strength grading of wooden boards.
